SPECIFICATION formingpart of Letters Patent No. 699,435, dated May 6,1902.

` Application led September 3, 1901. Serial No. 74,202. (No model.)

To @ZZ whom it may concern:

Be it known that I, CHARLES H. ASLING, a

citizen of the United States,residing at Spring-` tions thereof,substantially as hereinafter shown and described, and more specificallyset forth in the claims terminating this specification.

The most important object of this present invention is to provide adust-sprayingmachine capable of a wide scope of operation andusefulness, neat and attractive in appearance, light and compact in itsconstructiomand composed of the fewest number of mechanical partswithout sacrificing its usefulness or efficiency.

Another object is to provide`a dust-spraying machine which can easily beoperated by hand-power for the purpose of forcing a spray of dust to agreat height.

Another object is to provide a dust-spraying machine in which the dustor powder will not become clogged or banked in the machine, but will beautomatically fed to the exhaustnozzle and there controlled by theoperator, I

and still another object is to provide a dustL spraying machine whichwill be simple in construction, positive in its action, and which cancomparatively be manufactured and sold at a low price.

Other objects and advantages will appearV from the followingspecification and from the drawings forming a part thereof, as fully setforth hereinafter.

The details of the invention and the manner of operation of the variousparts will be fully set forth hereinafter and the novel features recitedin the appended claims.

In the accompanying drawings, forming a part of this specification,Figure 1 is a vertical section through the machine, taken on the line YY of Figsr, 4, and 5. Fig. 2 is a detail plan view of a portion' of themachine,

is mounted and is lplan view of the machine.

Similar letters and figures of reference denote like parts through theseveral views.

A represents a trestle on which my machine provided with legs B, asshown.

The left-hand end of the machine, as shown in the drawings, I will termthe front and ,the right-hand end of the machine I will term the rear,Figs. 1 and 5. Secured to the front end of the trestle and risingtherefrom and projecting rearward at Fig. 3 is a front the top is themain casting or frame 10 of my machine for supporting the various partsthereof.

11 represents a shaft mounted in the bearings`12 and 13. On the frontendof l1 is secured the main drive-wheel 14.

15 represents a shaft below and parallel with 11, mounted in the bearing16. On the end of 15 is secured a pulley-wheel 17, which is placed inalinement with 14, with a belt 18 connecting 14 and 17, as shown. Thewheel 17 is much smaller than the wheel 14, so that when the wheel 14 isrevolved by means of the handle 19 or otherwise the wheel 17 will `berevolved `at a much more rapid rate of speed than the .wheel 14.

i On the rear end of the axle 15 is secured a hub 20, with a multiple ofarms or paddles 21 extending out therefrom. Surrounding the hub 20 andthe paddles 21 is a case 22 with a neck 23 at its lower central point,with an opening connecting with the pipe 24. The pipe 24 projectsdownward through A and thence rearward underneath A to the rear end ofA, where it is provided with a flexible pipe 25, which latter isprovided with a nozzle 26. Should the wheel 14 be turned, the belt 18,acting on the wheel 17, will carry the axle 15 and it in turn the hub 20with the paddles 2l at a high rate of speed, thus causing a current ofair to pass rapidly through the pipe 24 and out at the nozzle 26.Secured to and rising from near the center of A in the rear of' 22 is around chamber 50 with its walls flaring outward, as shown, and a toppermanently secured thereto. At some IOO , vided with a handle 65.

convenient point in the top 51 I provide a, round orifice, through whichmaterial, such as dust, can be inserted into the chamber 50. Thisorifice I provide with a cap or cover 52. In the center of th top 51 Iprovide a bearing 53, through which the shaft 54 may revolve. In thebottom of 50 I secure a bracket 55, in the upper end of which is abearing 56, in which the lower end of the shaft 54 is jour-- naled. Inthe rearupper end of the casting l() is made a bearing 57 for thesupport of the upper end ol the shaft 54.

Secured on the shaft 54 on the inside of the chamber 50 are two sets ofblades or agitators 58 and 50, which are adapted to agitate and pressdownward on the contents of the chamber 50. The upper end of the shaft54 is connected to the rear end of the shaft 1l by a flexiblecoil-spring 60, as shown.

The bottom of the chamber 50 is provided .with a hole through the centerthereof, which hole connects with and forms an opening through the neck61 into the pipe 24. On the underside of the bottom of 50 I provide aplate 62, pivotally connected at 63, the rear end of said plateextending back to form the arm 64, the rear end of the latter being pro-On each side of the center of the plate 62 I provide a hole, each ofwhich are of a different size and which are arranged to come intoalinement with the hole in the bottom of the chamber 50 whenthe handle65 is placed at its extreme point to the right or left. When the handleis placed in the center, as shown in Fig. 2, the opening from 50 to 24is entirely closed. The handle 65 is provided with a correspondingmember 66, the two being pivotally united at 67 with a spring 66 betweenthem in order to keep their rear ends apart.

Extending across the frame A in the rear of 51 is the member 69, whichacts as a guide for the handle 65, with three holes arranged an equaldistance apart in its curved portion, as .shown in Fig. 2. The inner endof 66 is provided with a pin or point which is adapted to be engaged ineither of the three holes in 69. The drawings show the said point of 66in the center hole held in engagement therewith by the spring 68. Nowshould 65 and 66 be pressed together the pin or point of 66 will bedisengaged from the center hole in 67 and the handle can then be movedlaterally to the right or left and again locked in either one of theother holes, in which case the capacity of the opening from 50 to 24will beV changed either large or small, as desired. By theabove-described arrangement it can be seen that the amount of dustforced from 50 into 24 can be regulated and the liow maintained at thepoint desired. It can now be seen that while the wheel 14 is beingrevolved to turn the paddles 2l it is apparent that axle 11, inconnection with the coil-spring 60, connected to the shaft 54, willcause the agitators 58 and 59 to continually revolve and force a supplyof dust into the pipe 24, when it will be carried out through the nozzle26 by the force of the air put in motion by the paddles 21.

My improvements, as shown and described, are perfectly adapted toaccomplish the results for which they are intended, and it is evidentthat changes in and modilications of the construction herein shown anddescribed may be made and that analogous parts may be used to accomplishthe same results without departing from the spirit of my invention orsacrificing any of its many advantages.

The specific construction of the details of my machine, in which thenovel features are embodied, may be variously changed without alteringthe essential principles which are claimed as new.

The terms upward, downward, front, rear, and other similar terms areused for convenience of description, and it is not intended by their useto limit the arrangement of the parts to the relative positionsindicated.

I wish it to be distinctly understood that I do not dedicate any partofmy invention to the public and that I wish adequate and just protectionfor every feature of the machine and the various devices herein shownand described that is new and useful and which involve invention.

Having now fully shown and described my invention and the best mode forits construction to me known at this time, what I claim as new, anddesire to secure by Letters Patent of the United States, is-
